VEHICLE BUMPER.

Application filed February 27, 1325.' Serial No. 12,022,

rllhis invention relates to vehicle bumpers, and is illustrated as embodied in double bar bumpers iter automobiles.

One object ot the invention is to provi le a strong bumper in the 'form of an especially deep truss, by clamping together` the impact bars and a rear supporting device including one or two rear bars, by means oi a bolt passing through a trent plate and through a spacer ot' substantial length, the spacei being interposed between the rear taces ot the impact bars and the iront face of the rear bar device.

Another object of the vide an especially str ng bumper having rounded ends, by looping both impact bars rearwardly at bothends, and connecting the looped ends by a rear supporting device ot' one or two bars clamped tirmly to the centers'of the impact bars to form a pair o t strong spring trusses.

The above and other objects and features of the invention, including various novel and desirable details oit construction, will be apparent trom the following description ot two illustrative embodiments shown in the accompanying drawings, in which:

Figure 1 is a top plan view ot one illustrative bumper; y

Figure 2 is a front elevation of the same bumper;

Figure 8 is a vertical section on the line 3f?) ot Figure 1, showing the clamp; and

Figures 4, 5, and 6 are figures corresponding respectively to Figures 1 2, and 3, but showing a bumper of modiiied form,

In the arrangement of Figures 1, 2, and 3, vertically spaced parallel .impact bars 10 and 12, extending entirely across the front or rear ot an automobile, are bent or looped rearwardly at opposite ends, to form rounded ends for the bumper which are pleasing in appearance and which will not catcho-n adjacent cars. rlfhe rear bar device in this 'torni is a single straight bar 14, formed with eyes at its opposite ends which are interposed between eyes formed on the ends ot bars 10 and 12, the three bars being connected by vertical bolts 16 and 18 passing through the alined eyes. At the center, the bars are connected to form a deep truss by a clamp including a front plate 2O having a spacer lug 22 extending between the bars 10 and 12 and having upper and lower fingers 24 and 26 hooking respectively over invention is to proa pair the upper bar and below the lower bar. Between the two front bars and bar 14 is a spacer 28 oit substantial length, having a head 30 resting against the rear of the 'front bars and a head 32 resting against the front ot' bar 14. rFhe whole is clamped together by a bolt 34 passing through plate 2O and spacer 28 and through hole in bar 14. The bumper may be attached to the chassis trame by suitable brackets ot any desired form (not shown) mounted on bar 14 at opposite sides.

The bumper shown in Figures 4, 5, and 6 ditl'ers from that described above in that the rear supporting device comprises alined bars 4D and 42, bolted as described to the impact bars 10 and 12, and bent over at their adjacent ends to hook over the flanges of a channel-shaped rear clamp plate .44 through. which the bolt 34 passes. The ends of bars 40 and 42 abut against bolt 34 on opposite sides.

vWhile `two illustrative embodiments have been described, it is not my intention to limit the scope ot the invention to those particular embodiments7 or otherwise than by the terms of the appended claims.

I claim:

1. A bumper comprising, in combination, of vertically spaced parallel impact bars, a bar device connected at its opposite ends to the impact bars and spaced rearwardly therefrom and a central reinforcing clamp including a plate engaging the Jfront oi the impact bars at their centers, a spacer of substantial length comprising a cylindrical member having at each end lateral integralv extensions tor engaging the iront of said bar device and the rear ot the impact bars respectively, and a bolt passing through the plate and the spacer and clamping the bar device and the spacer and the impact bars all together.

2. A bumper comprising in combination, a pair of vertically spaced parallel impacty bars, each of which is looped rearwardly at both ends to provide rounded bumper ends, a. divided bar device connected at its opposite ends to the rearwardly looped ends of the impact bar and having the interior adjoining ends ormed with outwardly extending flanges; a channel-shaped clamp plate to engage the iianges, a 'front clamping plate, a cylindrical spacer having at one end webbed lateral extensions to bear against the rear of the impact bars, and at the other end a Harige for engagement With the adjacent ends of the said bar device; and a bolt passing through the lirst named plate, the spacer and the last named plate to clamp together all the said parts constituting the bumper.

3. The combination With a pair of vertically spaced rearwardly looped impact bars, of a rear bar comprising a pair of substantially straight bars connected to the said bars, the inner opposite ends of the bars being formed with outwardly extending flanges, a flanged plate to straddle the flanges whereby all the said bars are resiliently urged together; and a central reinforcing clamp including a plate engaging the front of the impact bars, acylindrical spacer formed at one end With oppositely disposed ears for bearing against the impact bars, and at the other end with a fiange for engagement with the said interior ends of the rear bar; and a bolt passing through the lirst named plate, the said spacer and last named plate, whereby the Various parts .of the bumper are locked together.

In testimony whereof l aflix my signature.
